Abstract
Electric machine has a rotor movable relative to a stator divided into stator segments, each having first and second transition regions and a central region between the transition regions. The stator segment has a yoke extending over the central region and the first transition region. Central groove webs in the central regions and first transition webs in the first transition regions extend from the yoke towards the rotor. The first transition webs end below the central groove webs. The stator segment has in the second transition region a transverse web from which second transition webs extend towards the rotor. The second transition webs end level with the central groove webs. A spacing of the first transition webs from the rotor at least corresponds to a spacing of a lower edge of the transverse web. Transition regions of adjoining stator segments overlap one another and are disposed one above the other.

11. An electric machine, comprising:
-
a stator; and a rotor movable relative to the stator in a direction of movement, said stator being divided into adjoining stator segments, when viewed in the direction of movement of the rotor, each of the stator segments having a first transition region, a second transition region, a central region arranged between the first and second transition regions, and a stator yoke disposed on a side facing away from the rotor and extending over the central region and the first transition region, said central region having central groove webs extending from the stator yokes toward the rotor, and said first transition region having first transition webs extending from the stator yokes toward the rotor and sized to end beneath the central groove webs, when viewed in a direction toward the rotor, with the central groove webs and the first transition webs respectively forming grooves which, when viewed from the stator yoke, are open toward the rotor and, when viewed in the direction of movement of the rotor, are respectively delimited laterally by two central groove webs, or by two first transition webs, or by one of the central groove webs and an adjoining one of the first transition regions, each said stator segment having on a side facing away from the rotor in the second transition region a transverse web from which second transition webs extend toward the rotor and form grooves which, when viewed from the stator yoke, are open toward the rotor and, when viewed in the direction of movement of the rotor, are delimited laterally by two second transition webs, said second transition webs sized to end at a same height as the central groove webs, when viewed in the direction toward the rotor, wherein the stator yoke has a lower edge which, when viewed in the direction toward the rotor, has a yoke spacing from the rotor, wherein the first transition webs has a spacing from the rotor, when viewed in the direction toward the rotor, said spacing of the first transition webs from the rotor being sized at least as great as a spacing of a lower edge of the transverse web facing away from the rotor, wherein the first and second transition regions of adjoining stator segments, when viewed in the direction of movement of the rotor, overlap one another and are arranged one above the other, when viewed from the stator toward the rotor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
